Solar (photovoltaic) panel prices
What you should know about this indicator IRENA presents solar photovoltaic module prices for a number of different technologies. Here we use the average yearly price for
In general, monocrystalline panels are capable of higher efficiencies than polycrystalline panels. Polycrystalline solar panels are also made from silicon, but their cells are made by melting together many fragments of silicon rather than from a single silicon crystal.
On the high end, we talked to a solar customer in Hawaii who spent $100,000 going solar. Dion in Nevada said their 10-kW system cost about $20,000, which is about the national average price for a 7-kW system. What else affects solar installation costs?
As of publishing, the average cost per watt is $2.84. Most solar companies set the price according to the solar system's wattage. A solar installation's “cost per watt” is a little like the “price per square foot” when you buy a house. It helps compare the value of solar energy systems in different sizes.
Solar batteries let you keep your lights on even when your local power grid is down. However, battery storage typically costs between $7,000 and $18,000. If you live in an area with frequent power outages, a solar energy storage battery is worth considering. Other equipment also factors into the overall price:
